Xpander Heat Detector

XPander A1R Heat Detector and Mounting Base

The Xpander Heat Detector range includes two types of heat detectors in order to suit a wide variety of operating conditions. The Xpander Static Heat Detector (CS) responds only when a fixed temperature has been reached, and the Xpander Rate-of-Rise Detector (A1R) has a fixed upper limit, but in addition, measures the rate of increase in temperature.

  • Can be used in applications where smoke detectors are unsuitable.
  • Ideal environments that are dirty or smokey under normal conditions.
  • Bi-directional (monitored) radio platform.
  • Easy to install.
  • Powered by two independent battery packs.
  • Five-year battery life using standard AA alkaline batteries.
